Are you really so uneducated that you've never heard of error bounds?
Or do you really think we've measured the peed of light under all galactic or universal conditions?
Or that the Earth's Gravity attracts at 9.8m/ss?!
It doesn't and you can look up the variance in the Earth's gravitational field on Google. Ask a third grader if you do't know how to do a proper search.

"Are you really so uneducated that you've never heard of error bounds?"
See post #327. Moreover, science has proven many, many things under many, many circumstances.
In contrast, you claim that science has proved nothing.
You are, and will remain, wrong.
